Emitter modulator is one of many ways you can construct a modulator. It is classified as an active modulator because a BJT transistor is used in its construction. Passive modulators uses diodes for its operation. Here an emitter modulator design is …
A Practical Guide from Basics to Real-World Design Wireless Power Transfer (WPT) is no longer limited to smartphone chargers. Today it is used in electric vehicles, medical implants, IoT sensors, robotics, and industrial systems . However, designing…
I salvaged some SBL3040 schottky barrier rectifier diodes from my old desktop power supply. These can be useful in diy switch mode power supply circuits such as DC to DC converters, that is boost converter, buck converter. They can also used used a…
Here’s a clear, practical guide to connect a USB–TTL converterwith a Bluetooth HC-05 module for configuration and testing. This is the most common setup used before connecting HC-05 to Arduino or ESP boards. 1. Know the HC-05 Pins (important) Typi…
I was thinking about what could be the relation between a DC motor and an LC tank circuit because both of them are fundamentally based on electrical and electromagnetic principles. A DC motor primarily operates with direct current and converts elect…
Yesterday I went to the site on a mountain where I am trying to distribute internet. I had lot of works there so I went early than usual. I had a good reliable wireless point to point link between the tower in the office to the site with two Power …
I have been working on making a wireless network for internet distribution and have been recording some of my works. I wrote about Ubiquiti Lite AP Link: Line of Sight vs. Fresnel Zone and Struggles with Ubiquiti Lite AP and PowerBeam Connections .…
Earlier this week, I shared how I was struggling to connect two Ubiquiti Lite AP 120 antennas . After two more days of attempts, I’m still facing the same issue between my office and home, which are about 350 meters apart. At one point, I dismounted…
